    摘要： A disaggregation monitor is provided of an electrical power system having an electrical circuit with branches and loads. The disaggregation module includes a memory configured to store instructions and a processing device disposed at the location and in communication with the at least one memory. The processing device upon execution of the instructions is configured to a) iteratively and automatically control or instruct to turn ON one branch set having one or more branches of the plurality of branches at a time while remaining branches of the plurality of branches are turned OFF to isolate the branch set until all branches of the plurality of branches have been included in at least one isolated branch set, b) obtain an electrical signature of each isolated branch set; and c) disaggregate at least one load of the plurality of loads using two or more of the electrical signatures obtained.

    摘要： Disclosed herein is an intelligent switchable device for selectively conducting electricity based on the condition of a branch circuit. The device contains at least one sensor for producing a signal indicative of a condition. The device is capable of transmitting data and communications as well as receiving data, including remote instructions and rules. The device is capable of storing rules for determining whether to render the switch conductive or non-conductive. An optical prong detector is provided to determine whether both the hot and neutral prongs of a plug have been inserted into the receptacle. The receptacle provides conductance upon determination of insertion of a plug into the receptacle. Additional features include GFI detection, current detection, heat detection, warning lights and an audible alarm. The receptacle includes communication abilities with remote devices to transmit data indicative of the state of the device.

    摘要： The invention relates to a base element (ST1, ST2, ST3) for receiving an overvoltage protective module (M1, M2, M3) for use in a bus system, having a first bus connection arrangement (BK1) for contacting a first bus potential (L1), a second bus connection arrangement (BK2) for contacting a second bus potential (L2), a third bus connection arrangement (BK3) for contacting a signal bus (L3), wherein the signal bus in a first state indicates the occurrence of a fault and in a second state indicates the non-occurrence of a fault, wherein a fault indicates a missing or incorrectly received or faulty overvoltage protective module (M1, M2, M3), wherein the first and second bus potential are to be used to supply arrangements on the overvoltage protective module (M1, M2, M3), wherein the base element further comprises an electronic monitoring arrangement (UE1), wherein the electronic monitoring arrangement (UE1) identifies whether an overvoltage protective module (M1, M2, M3) is received, wherein, if an overvoltage protective module (M1, M2, M3) is received in the base element (ST1, ST2, ST3), the second state is signalled via the signal bus, and, if no overvoltage protective module (M1, M2, M3) is received in the base element (ST1, ST2, ST3) or if the overvoltage protective module (M1, M2, M3) is received incorrectly or if the overvoltage protective module (M1, M2, M3) is faulty, the state of the signal bus remains unchanged, wherein the base elements (ST1, ST2, ST3) can be clipped onto a mounting rail (TS1, TS2), and the first bus potential (L1), the second bus potential (L2) and the signal bus (L3) are guided in a recess in the mounting rail (TS1, TS2).
